js-keccak-tiny

Keccak tiny wasm binding in javascript.

Keccak tiny

Keccak tiny is a c implementation of keccak, the original repository https://github.com/status-im/nim-keccak-tiny.

Install

• install library

$ npm install js-keccak-tiny

Build with emscripten

You can build keccak-tiny wasm yourself with emscripten. To konw how to install or setup emscripten on your computer, please check their documentation https://emscripten.org/docs/getting_started/index.html. I build two version of keccak-tiny - nodejs and web. The only difference between two version is that there is no file system in web version.

$ sh build.sh

After build wasm files, you should build javascript library again.

$ npm run build

Usage

• Hash message

// for nodejs
const keccakHashAsync = require('js-keccak-tiny/dist/node-bundle')

// for browser
const keccakHashAsync = require('js-keccak-tiny/dist/browser-bundle')

const msg = Buffer.from('It works!', 'utf8')

// initialize the library
keccakTiny = await keccakHashAsync()

let hash = keccakTiny.keccak256(msg)
// do something to hash...
